append text at every 94 line. 1

[dbase77]

Hi,

Is there a way to append text at every 94 line in a file? I have a big file. At every 94 line I have "^M". What I want to do is add "^L" before it. So it will look like "^L^M". Can anybody help with this, please? I tried to google but no luck so far.

Thank you in advance.

regards,

A starting point:
awk 'NR%94==0{sub(/\r/,"\f\r")}1' /path/to/input > output

Hope This Helps, PH.

Hi,

Thank you for replying. Dont quit understand the first part. The second part "sub" is for substitution for \r (carriage return) and \f\r (formfeed and carriage return). But when I run it I got error:

awk: syntax error near line 1
awk: illegal statement near line 1
awk: syntax error near line 1
awk: bailing out near line 1

I'm a newbie. Please go slow on me.

If you have it, try nawk (or gawk).

Thank you.

hmmm strange. When I print the file, it prints extra page at every ^L^M. Do you know why?

Yes, ^L is a FormFeed.

The reason I put ^L at every new page (line 94) was to print the file properly. If not, it won't print when it reaches to new page, instead it just add blank line from previous page to it owns page. So on the second page and so on, I got this huge empty page. If you understand what I mean. So, how do I get rid this extra page and print the file properly? Any ideas?

Thanks again.

Try substituting the ^L for the ^M and see what happens.

Or perhaps this ?
awk 'NR%94==0{printf $0"\f";next}1' /path/to/input > output

needcoffee,

Same effect I'm afraid. It still prints extra page.

What are your queue settings for this printer and what type of printer? Perhaps your settings need a tweak.
